Application filed June 27, 1921.

To (ZZZ whom it may concern: 7

Be it known that I, BURTT J. HUBBARD, a citizen of the United States, residing at liokomo, in the county of Howard and State of indiana, have invented certain new and useful Improvements in Radiator-Gap Attachments, 012' which the following is a specification.

This invention relates to improvements in radiator cap attachments, and has for its object to provide a handle of ornamental appearance, and or" such construction as to be capable of attachment to any standard automobile radiator cap by making only slight alterations therein, and which when so attached afi'ords a convenient grip for turning said cap to or from normal position on the radiator spout.

A further object of the invention is to provide a cap handle of such construction that it may be used in connection with a standard temperatureindicating device, or

so-called motometer, or with other ornamental devices of various designs commonly used at the present time.

A still further object is to provide a looking device which will prevent the unauthorized removal of the cap and handle and of the ornament used therewith.

Other advantages relate to features of construction and arrangement which will more fully hereinafter appear.

In the drawings- Figure 1 is an elevation of the cap handle;

Fig. 2 is a vertical section of the cap handle. shown constructed integrally with a centrally disposed ornament, and of the radiator cap, showing the locking means;

Fig. 3 is a section on the line 3-3 of Fig. 2;

elements throughout the drawings, in which 10 indicates, generally, the radiator cap handle, having a base 11 provided with a vertical bore 12 and carrying oppositely flaring horns 13 terminating in balls 14. It will be understood that the particular design of handle and ornaments herein shown and described is for the purpose o1": illustration only, and that other forms may be substituted without departing from the spirit of the invention. An ornament 15, see Fig. 1--of any desired design, is adapted to be mounted on the handle 10 and both said members are securely attached to any radiator cap.

When the ornament 15, or indicator 20, is made non-integral with the cap handle 10, as shown in Figs. 4 and 6, respectively, the lower base portion 17 of said ornament or indicator is provided with a hole 18, of small diameter. adapted to register with a corresponding hole 18 of the handle when said ornament is secured in assembled rela tion thereon. A small pin 19 is housed within said registering holes, and prevents rotation of the ornament 15 with respect to the handle member 10.

The ornament 15, or indicator 20, has a threaded depending stem 16. which passes through the opening 12 in the handle 10 and through an opening 21 provided therefor in the radiator cap 21see Fig. 2, for example. A second hole 10 is provided in the lower side of the handle, which is adapted to register with a corresponding hole 21 in the cap 21. A second pin 21" is provided to prevent rotation of said handle with respect to said cap.

A nut 22, coacting with the threaded portion of the stem 16, draws the ornament 15 or indicator 20 and the handle 10 into nonrotatable engagement with the cap 21. When the handle is so secured to the cap, the latter may be readily turned to or from normal position on the spout 23 by means of said handle, as will be obvious.

Instead of using the hole and pin method for providing against relative rotation of the cap 21 and handle 10. as above described, the stem 16 of the ornament- 1 whether the ornament 15 or indicator 20 be made integral with the handle or notmay be provided with a knurled portion 16* (see being threaded, as shown.

Figs. 4 and 5) adjacent its upper part, which portion should be slightly larger than the hole 21 in the cap member provided therefor. The stem is forced into said hole, and the knurled portion of the stem bites into and thus provides non-rotatable contact with said cap.

Referring to Fig. 2, wherein the ornament 15 is shown integrally constructed with the handle and the two members secured to the radiator cap 21 by the means above described, a headed pin is shown extending through the hole 2 1 in the ornamental member and stem 16, the lower end of said pin A horizontal plate 25, having a flange 25 on its upper side surrounding the hole 26 which extends therethrough, is attached to the pin 23 by means of a nut 27 and washer 28. When in assembled relation the lower portion of the stem 16, which is flattened on two sides to correspond with the flattened hole 26 in the plate 25 (see Fig. 3) projects a short distance into said hole, and thus has a nonrotative engagement therewith. The ends of the plate slide vertically in slots 29 provided in the sleeve 30, which is inserted in a spout and secured thereto by rivets or other means.

When the members are in assembled relation, as shown in Fig. 2, the cap 21 cannot be turned, because the lower portion of the flattened stem 16 is engaged by the boss or flange 25 of the plate 25, which is held against rotation by the slots 29 in the sleeve 30. By lifting the pin 23, however, the plate 25 is raised out of engagement with the slots 29, sufficient clearance being provided between the lower end of the stem 16 and washer 28 for such upward movement.

When the plate is thus raised out of engagement with the slots the cap may be removed in the usual manner. The spring 3) tends normally to hold the plate in lowermost position, and serves also to prevent it from rattling.

To prevent unauthorized removal of the cap and ornaments attached thereto, a lock 31 is provided at a suitable place, preferably in the ornament, said lock being adapted to thrust a locking bolt 32 upon the turning of a key 33 into a slot 3% provided in the pin When so locked the cap 21 will be secure against theft, as will be obvious.

It will be seen that the cap handle above described may be attached by the means disclosed or otherwise to a radiator cap, and when so attached affords not only a handle for turning said cap relative to the radiator filling spout, but also has a desirable ornamental effect, which may be supplemented by combining therewith a centrally disposed ornament or temperature indcating device.

Although I have shown and described certain forms of my invention, it will be obvious that modifications may be made there .in without departing from the spirit thereof; and I do not therefore wish to be restricted to the forms herein shown and described, except where limitations appear in the appended claims.

I claim 1. The combination of a cap with a handle therefor, said handle having a central aperture and being provided with a hole on its upper and lower sides, an ornament or the like having a stem passing through said aperture and through the top of said cap to secure said members together, and pins positioned in the holes of said handle and adapted to enter registering holes in said ornament and said cap to prevent relative rotation of said members.

2. The combination of a spout with a rotatable cap, a handle secured thereto and having a depending stem extending therethrough, a vertical recess within said spout, and means engageable by said recess for preventing rotation of said cap.

3. The combination of a spout with a re movable cap therefor, a handle secured to said cap, said handle having a depending stem, a plate movable vertically on said stem, means adapted to engage said plate to prevent rotation thereof, and means extending exteriorly of said handle for elevating said plate above said engaging means.

In testimony whereof, I have subscribed my name.

BURTT J. HUBBARD.
